Projection Photography

Here the optical image that the telescope's optics deliver is further magnified by the use of a magnifying lens. In most cases an eyepiece is used for this purpose. (therefore the name) What follows is a collection of pictures of the planet jupiter during the impact of the comet in 1994. In this case the film was replaced with a video camera as a detector.
